Nanotechnology • What is Nanotechnology? “Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications.” “Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.” National Nanotechnology Initiative, 2007

Richard Feynman - “Grandfather” of Nanotechnology Dr. Richard Feynman, one of America’s most notable physicists, 1918-1988. History of Nanotechnology “There is plenty of room at the bottom.” (R. Feynman 1960) “Can we write the Encyclopedia Brittanica on the head of a pin?” 1985 - graduate student wrote a page from A Tale of Two Cities 1/160 millimeter in length using Ebeam lithography Current status of “nano-writing” technology: E-beam lithography: resolution 10nm
Example “How do we write it?” “How do we read it?” Fabrication methods: • Top-down: Lithography, pattern transfer, “sculpting” Problems: Definition of feature size, alignment • Bottom-up: Self assembly Problems: controlled arrangement, regularity Imaging methods: • Optical Problems: wavelength of light on micron scale • Electron-optics: Problems: Expensive, complicated • Scanning probe methods Problems: slow due to scanning
History of Nanotechnology Buckyballs Three gentlemen—Harold Kroto from the University of Sussex, Robert Curl and Richard Smalley from Rice University—were awarded the Nobel Prize in Chemistry in 1996 for their discovery of a new composition of carbon, Carbon 60. Fullerenes Carbon 60 was named after Richard Buckminster Fuller, who went by the nickname “Bucky.” A “Buckyball.” Dome over biosphere in Montreal
Biology • DNA/RNA – 2-3nm per base pair – 109 base pairs for human genome • Proteins – 100K different in human – “self-assembles” • DNA-computing • DNA-based self-assembly • ATP motors Chemistry • Molecular diodes • Molecular switches • Block Polymers • Fluidic self-assembly • Molecular design Application Areas in Engineering Physics • Quantum mechanics • Scattering Materials • Carbon Nanotubes • Multifunctional materials • Smart materials • Nanostructured catalysts
Application Areas in Engineering Electrical Engineering • VLSI • Lithography – Top-down assembly – Easily to 65nm, controlled gates to 15nm, – Thicknesses to sub-1nm! • Transistor • Electronic nanotechnology • Nanocomputing Robotics • Integration • Actuation (e.g., surface tension) • Power systems • Sensing • Emergent behavior
